Abstract: The observed sea-level pressure variations in Senj and pressure dilference Zagreb-Senj are presented for 197 observations in 17 case studies considering only the most severe bora storms in Senj from the period 1957-1986. Using Smith-s 1985 hydraulic theory with the continuous stratification model, mountain drag is calculated predicting the pressure difference across the mountain in these bora evbnts.

It is shown that the theory can predict well the pressure difference in cases when the atmospheric state is close to the idealized modeling structure. However, due to constraints in the presented model there is a relatively-small sampling of such cases, although the real atmosphere allows some reasonable modifications of hydraulic

parameters which would be unnecessary if the flow were truly two-dimensional and steady.
